InitialContext for EJB 2.x JNDI on Glassfish v2ur2 under Windows Vista

Hi,

I am working under Windows Vista Home Premium, Glassfish v2ur2 and developing on NetBeans 6.5. I have been visiting the threads in the forum and some pages googling over there. I have found some answers but no one solve my problem.

The furthest I have got is the following code,

private static InitialContext getInitialContext() {
        InitialContext ic  = null;

        try {
            Properties props = new Properties();
            props.setProperty("java.naming.factory.initial",
                "com.sun.enterprise.naming.SerialInitContextFactory");
            props.setProperty("java.naming.factory.url.pkgs",
                "com.sun.enterprise.naming");
            props.setProperty("java.naming.factory.state",
                "com.sun.corba.ee.impl.presentation.rmi.JNDIStateFactoryImpl");

            ic = new InitialContext(props);
        } catch (NamingException ex) {
            ex.printStackTrace();
        }
        return ic;
    }

I am trying to call JNDI EJB 2.x but this code gives me a NamingException. It is possible that I do not include the necessaries jar into the project, or that the code should be wrong.

This is the server log,

Does it mean that I need any jar or maybe the code is wrong?

Thanks in advance,

Hi Jose,

You need to add the following file to your project classpath and I think you should use com.sun.appserv.naming.S1ASCtxFactory instead of the com.sun.enterprise.naming.SerialInitContextFactory, honestly I do not remember the difference right now.

../glassfish-v2ur2/lib/appserv-rt.jar

I have no idea about what does it mean.

Have you?

Thanks for your interesting and best regards,

[Masoud Kalali]

Can you explain what you are going to do? you need to initialize the context factory when you are outside a preconfigured container, for example when you want to access the container managed objects from outside the container. You can take a look at this blog entry to understand how we can use the contextfactory to access container managed resources.

 Hashtable properties = new Hashtable(2);
        properties.put(Context.PROVIDER_URL,"iiop://127.0.0.1:3700");
        properties.put(Context.INITIAL_CONTEXT_FACTORY,"com.sun.appserv.naming.S1ASCtxFactory");
        try {
            ctx = new InitialContext(properties);
        } catch (NamingException ex) {
            ex.printStackTrace();
        }

this is a simple code for initializing a context factory for GlassFish. you can find a more extensive explanation at http://weblogs.java.net/blog/kalali/archive/2006/05/step_by_step_to_2.html

Hello Masoud,

My application is a web application. I have the EJBs in a jar file and the client is the web application. I have got thi InitialContext but I have not the lookup JNDI of the EJBs. It is because the descriptors. I do not know how to declare the EJBs in ejb-jar.xml and sun-ejb-jar.xml This is what I have done,

Excuse me if I do not know enought but I am trying to learn.
On this descriptors, how do I have to call the EJBs home interface?

Because just reach this point I think I can go on alone.
